Abstract
In the last decade, Paraguay has made progress in the development of health-related research involving human subjects. This entails the obligation of the State to ensure that research is conducted ethically: protecting the dignity, rights and welfare of the participants, scientific integrity and adherence to international ethical guidelines. Research Ethics Committees are the main instance or resource to guarantee the aforementioned obligation. In view of the above and the context lacking adequate regulation in which research is currently carried out in the country, this article will defend the ethical imperative of establishing an accreditation system for research ethics committees. To this end, its necessity will be presented and justified and some objections related to the ethical imperative defended will be answered, such as the per se value of the accreditation of research ethics committees in the protection of participants, the investment of time and bureaucracy involved in the accreditation processes and the incipient regulatory framework for research on human beings in Paraguay. Finally, it will be proposed to strengthen the governance of research ethics in the country, as the main means to establish, implement and supervise an accreditation system for research ethics committees.
